Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

A method for matching identical person or objects from multiple visual images from cameras in different places, There are two main components: 1) Learning based patch correspondence structure estimation for camera pair, which further consists of a) Building patch set with structure; b) Learning to set the value for the patch correspondence map 2) One-to-one assignment based patch matching and overall scoring, which further consists of a) Combine both learned correspondence structure and patch visual similarity to set the patch-to-patch similarity for all pairs; b) Impose one-to-one patch matching to obtain the ideal matching and associated overall score

view correspondence identification

The problem this disclosure addresses is to recognize identical people from multiple cameras views. It has many applications such as in video surveillance.

The system overview of our approach is as follows:

The first component is learning the correspondence structure. The embodiment is as follows:

1) Set up the patch set by a certain order

2) Perform patch based matching such as [1] to find a reasonable mapping M (not perfect) between the probe sample and one of the positive samples (usually with different poses)

3) Compute the score S of each matching pair between the probe image and one of the positive samples from gallery images

4) Add up each S*M to obtain the learned correspondence structure given k-1 positive samples
